Bug: amount of projects, educations etc. not updating after creating a new one

**Description**
When creating a new station or project etc. the count displayed at the top doesn't get updated and it only updates when the user refreshes the site.

**TODO**
- [ ] Count should be updated right after
- [ ] Write/Update Tests
